ShowSize is a powerful disk space utility that makes it possible to find large, space-hogging folders and files on local or network disk volumes. ShowSize delivers the power that demanding users need to get a clear picture of disk space usage on their hard drives. As a result they can find out what folders, file types and files are consuming the most disk space. The users can then examine these in further detail by going deeper into ShowSize reports that display the disk space related data in a hierarchical tree list. The end result is that the users are in a better position to identify and remove unwanted folders and files to get more disk space for the new and useful stuff. Advanced users such as network administrators can take advantage of this information to monitor the disk space consumed by various users in their organization, and can produce helpful reports that avoid system bloat and inform these users about the details of their disk space usage. ShowSize is heavy-duty software that can scan terabytes of disk space and can show lists containing millions of items. This is possible by an innovative virtual listing technology that it uses.
